摘要： In an aspect, the present disclosure relates to a relay node (RN) operatively coupled with user equipment (UE), wherein the RN is configured to create one or more tunnels to enable transmission of data messages and control messages from the UE directly to a packet data network gateway (PGW). The present disclosure relates to methods and systems for tunneling user equipment (UE) traffic by creating one or more tunnels between a relay node (RN) and packet data network gateway (PGW) to prioritize control messages over data messages, wherein the one or more tunnels are created when the UE gets attached to the relay node (RN). Further, tunneling of the one or more control/non-access stratum (NAS) messages to the PGW can be performed over one of the higher priority tunnels such that when the NAS messages are received at the PGW or HGW, they can be forwarded to a mobility management entity (MME).

摘要： Aspects of the present disclosure aim at providing three pseudo-orthogonal waveforms that can be used for transmitting 3n bits (n bits over each waveform) at a given frequency. Use of such three pseudo-orthogonal waveforms can be used in applications such as QAM to create a 3-dimensional QAM, along with use in other like applications such as in Orthogonal frequency-division multiplexing (OFDM), Quadrature Phase Shift Keying (QPSK), Binary Phase Shift Keying (BPSK), among others. The three pseudo-orthogonal waveforms can in general be used in any application where complex number algebra is used, and can help increase transmission capacity by additional 50%.

摘要： A method for Independent resource request for initial NAS signaling in a communication network comprising of transporting service request message of both the UE and RN via Base station to management entity of Evolved Packet Edge (EPE) within Evolved Packet Core (EPC), as a signaling message over uplink channel referred to as “Independent Resource Request” (IR Request)’ message. The service request response message from one of the management entity of EPE or management entities of UE and RN within EPC are transported as a signaling message to EPE via Base station over the downlink channel referred to as “Independent Admission Response” (IA Response). This manages bearer setup signaling as a single loop, by transportation of “IR Request” signaling message over uplink and receiving “IA Response” signaling message over downlink channels.
